Abstract (en)
[origin: WO2018096228A1] Method for controlling a hybrid motor vehicle powertrain fitted with a gearbox of Locobox type. The method comprises the following steps: determining,for each electric machine and for the internal combustion engine, a torque differential defined as being the absolute value of the difference between a torque setpoint at the preceding instant and a target torque setpoint at the end of the reapplication of torque, then a Boolean variable indicating the status of the torque reapplication phase and a Boolean variable indicating the end of the torque reapplication phase for the internal combustion engine as a function of a first instant, defined as being the instant of the start of reapplication of torque and of a second instant defined as being the instant of reapplication of torque, and torque differentials for each electric machine and for the internal combustion engine, as a function of the comparison between the present instant and the first and second instants, a raw torque setpoint, an unsaturated torque setpoint, a saturated torque setpoint, and an intermediate torque setpoint are determined, then the torque setpoints for the electric machines and for the internal combustion engine are determined as a function of the determined values and variables.
